Description

Toilet seat

Technical field

The present invention relates to a kind of toilet seat, it has the separate chamber of the reception of being respectively applied for and discharging urine and ight soil, this chamber is arranged on below the shared stand, this toilet seat is equipped with a valve, this valve has covered the ight soil chamber at least and has been suitable for moving by a mechanism, and described mechanism is activated by the user of toilet seat.

The present invention is specially adapted to not have sewage and/or feedwater public utility and can not uses lavatory in the zone of general flushing toilet seat.

Background technology

If desired urine and ight soil are separated, also can use this toilet seat, can make urine directly be discharged into discharge outlet or independent collecting tank like this, and as fertilizer sources continues to use with decomposition can to collect ight soil individually, perhaps directly abandons from the urine chamber.But through adjustment seldom, the ight soil part can be connected to a ready-made outlet.

The purpose of this invention is to provide a kind of toilet seat, it is easy to install, and does not need water, does not also need to install sewage pipe, and very suitable from ergonomics, also is convenient to clear up and can separate simultaneously.

When adopting chemical toilet seat, from aesthetic, many users greater than a dating see that the faeces container of toilet seat can be displeased.

In order to eliminate this inconvenience, different types of valve has before been proposed, these valve can be activated by the user by operating mechanism.The example of these toilet seats is for example learnt from publication application SE 179,133 and 386,585.The shortcoming of these designs is their very difficult cleanings, means to have the foreign odor of making us.In these two kinds of structures, pollute the parts of valve mechanism possibly.Because the valve mechanism parts are movable, so clear up very difficult.

In addition, SE 386,585 disclosed structures can not be separated ight soil with urine.SE 179,133 disclosed structures but can make ight soil separate with urine when having adopted a kind of ight soil and the shared chamber of urine with special convex curve shape.Thus, imagination urine flows down and is led in the independent liquid collecting container along leading edge.

But discharge urine or urine amount are very big if the user exerts oneself, and then this structure can not be guaranteed separating effect.In this case, the diffusing situation of spattering and fall into faeces container of urine may take place, also may under the very anxious situation of urine stream the situation that urine is left convex wall and flowed into faeces container take place.

The common drawback of these two kinds of systems is: when faeces container was closed, they can not provide independent men's urinal.Promptly allow to adopt these two kinds of structures that illustrate as urinal, its result can only be the valve of making dirty, thereby produces peculiar smell after causing.

In addition,, make valve be held open state simultaneously with the both hands of free time, thereby be difficult to for cleaning, thereby will hinder cleaning above-mentioned disclosed toilet seat near the inside of toilet seat because the user is in order to clean.

In disclosed structure, do not provide special device to guarantee that the user can use toilet seat very comfily aspect ergonomics, and can reduce or avoid cosily using this equipment under the situation of unnecessary pollution.

Summary of the invention

The objective of the invention is to point out the sort of toilet seat mentioned in a kind of introduction in front, it has solved the problems referred to above, and a kind of toilet seat of safeguarding and cleaning of being easy to is provided simultaneously, and the man is used this toilet seat when standing as urinal.

Above-mentioned purpose is achieved by the toilet seat in type described in the introduction, this toilet seat is characterised in that: valve is made of the cover plate that rotates around pivot, described cover plate is arranged near in the plane below the stand, and be suspended on the pivot of perpendicular, and described pivot is positioned on the framework of ight soil and urine chamber, so that described cover plate can rotate between it covers the position of the position that open wide, that be roughly circular opening of ight soil chamber and each side of opening both sides up; Operating mechanism is installed on the framework and comprises a spring-loaded cylinder, this cylinder extends through the top side of framework, and overcome the activation that is used for of spring force by the downward load that directly is added on the stand, described cylinder comprises first tappet, the first tappet surface interaction of this tappet and rotatable sleeve pipe, described rotatable sleeve pipe is installed on the described framework, and described sleeve pipe has the rotational fixation device with the rotating plate engagement; The opening of urine chamber is not covered by valve, with respect to toilet seat, looks from user's position, and above-mentioned opening is positioned at the front end of ight soil opening.

Operation is very simple, when the user is sitting on the stand, his weight overcome spring action and with cylinder to pressing down, make tappet act on the tappet surface of rotatable sleeve pipe.Thus, cover plate all rotates to the side, and the opening of ight soil chamber is come out.

Because cover plate all is arranged in the plane and in the lower, planar near the toilet seat stand and rotates, so can not pollute cover plate and the operating mechanism that is positioned at ight soil chamber outside.Although be provided with groove near the position below the stand in order to hold cover plate; but when cover plate turns to the side of well-bucket (be preferably in described well-bucket is provided in the ight soil chamber) outside; groove also is positioned at very high position and is protected below stand, even also can not pollute under the situation of user's diarrhoea.

If someone wants toilet seat is used as urinal, also be easily, and needn't make the user see the ight soil jar in revolt.The opening of urine chamber is positioned at the appropriate location in ight soil chamber opening the place ahead side by side and always we opens, and with the location independent of cover plate.

Above shared stand, toilet seat can have the lid that covers stand with known manner, has stopped that thus the user is to the sight line of urine chamber and to the sight line at the cover plate top in the ight soil chamber.

In order to obtain suitable embodiment, the opening size of toilet seat urine chamber preferably and ight soil chamber opening measure-alike or bigger.Compare with other separate type toilet seat schemes, this is very important and is remarkable different feature, because the size of urine chamber is littler usually in other schemes.The example of this a kind of structure in back can be learnt from patent WO95/32658.

Toilet seat of the present invention can be contemplated to different patterns.But according to a preferred embodiment of the invention, it is characterized in that: framework is made the shape that is roughly egg, and described egg type is equivalent to have parabolical semicircle; The ight soil chamber is arranged on circular end, is roughly cylindrical and has to be roughly circular opening; The urine chamber forms in parabola shaped terminal and have a shape that is roughly half egg, and its opening is roughly parabola shaped at front end, and the rear end is limited by the circular wall that extends the ight soil chamber in the egg type; The ight soil chamber comprises an independent well-bucket; The top edge of confining wall is lower than other edges of urine chamber and framework top side coplane slightly; In each side to egg type wall transition position, confining wall all has a vertical groove, makes the outer rim of well-bucket can cover the top edge zone of urine chamber.

According to this design, clearly the urine chamber can ad hoc be used as urinal, is very easy to cleaning simultaneously again.The pattern of this recommendation has obviously reduced the amount of loosing and spattering, and makes urine can be retained in the urine chamber and by the opening of urine cavity bottom and discharge that the urine of discharging from described opening can be imported into independent container.Therefore, when the man was used as urinal to toilet seat, from the aspect of avoiding loosing and spattering, clearly the semicircle rear wall in the urine chamber was very favorable.In addition, find out obviously also that when the woman used toilet seat with sitting posture, even it is very anxious to urinate, diffusing spattering also can be reduced in the front portion of parabola/egg type.Urinal also can have one along the pond longitudinal extension, can be the separator bar that mays be seen indistinctly, and in the sloping edge zone that its each side all has points upwards, flow because it is urinated to side separations/refraction, spatter thereby reduced to splash down and loose.Separator bar can be simultaneously as user's sight line, and this for example is related to the problem that the user consumes some liquid that influences a little.

Under the background of the specific embodiment of rear wall, promptly the outer rim of ight soil well-bucket covers under the situation on the groove between urine chamber and the ight soil chamber, and urine might flow to downwards in the space between ight soil well-bucket and the ight soil chamber.Because limiting wall is lower than other edges, thus outer rim might be arranged on the upper edge of this wall, thus make the top side of outer rim be lower than the top side of framework slightly.Therefore, the freely-movable of rotating plate can not hindered, and they can be pivoted in the space between well-bucket top side and the framework underside.In addition, the isolation edge of reduction will be very suitable aspect ergonomics, because it provides bigger space for male sex user's vitals.

Compare with traditional toilet seat stand, stand of the present invention has less relatively ight soil opening, can correctly be sitting on the stand in order to guarantee the user, is preferably in the thigh location of groove with the guiding user is provided on the stand.By guaranteeing that the user is correctly taken a seat, can reduce or eliminate the sort of the loosing that means the toilet seat of to make dirty and spatter risk.

Optimum implementation is to make being rotationally connected of forming between the rotatable sleeve pipe of operating mechanism activate cover plate by an one control lever.Form also can directly be fixed to cover plate on the rotatable sleeve pipe as an alternative.Can provide the rotating fixture of following form, i.e. the collaborative mutually running of corresponding sides marginal pore in the marginal portion of sleeve pipe and cover plate or the control stick.Form also can form rotating fixedly connected by the threaded connector that firmly screws between sleeve pipe and lid and/or control stick as an alternative.

When adopting control stick, can allow it activate the pin that is positioned on the cover plate, form displacement, make cover plate or a plurality of cover plate move to the position that they are opened with the effect that overcomes spring.But preferably the control stick that has a groove (being used to admit the pin on the cover plate) by employing opens or cuts out, so that form a kind of positive motion.Thereby the motion in described groove will force cover plate to forward it to and open and close the position by pin.

When the useful space of stand below, promptly the space that will hold cover plate is reduced, preferably provide two cover plates that can rotate to ight soil opening both sides.These cover plates preferably are suspended on the pivot, when with respect to toilet seat when look in user's position, described pivot is positioned at the rear portion of framework.These pivots will be arranged on the position of the central plane that nestles up toilet seat, make cover plate to rotate to the side.The operating mechanism of each cover plate all is preferably disposed on the position of each side of urine opening.Therefore, they are away from pivot.Like this, the power of using when being activated on the close position of pivot with cover plate is compared, and rotatablely moves by using less relatively power, just can forming.

Form as an alternative, can also be equipped with pivot and operating mechanism as integrated apparatus, make the activation of pivot cylinder, and then the interaction on first tappet and the first tappet surface can be impelled cover plate directly is installed and rotate with that cylinder that rotates around operating mechanism.But,, need on the tappet surface, apply relatively large power in order to form the required moment of rotating plate.

Therefore, preferably operating mechanism is arranged on each side of urine opening.In addition, also operating mechanism to be arranged on the middle part of stand, promptly bear the place of user's major part weight.Thus, the weight that has guaranteed the user can pass to operating mechanism well.When toilet seat was used by children, this was very favourable.

Under common operating position, the cylinder or the column that stretch out the operating mechanism of framework top side will be arranged on following position with respect to stand, promptly when first tappet is surperficial by the tappet of rotatable sleeve pipe, described cylinder or column are pressed against open position, and described rotatable sleeve pipe preferably is positioned at the tappet groove.Otherwise the load that discharges on the stand then can close cover plate under suitably big or small spring action, on the cylinder or cylindrical rod member of described spring action in operating mechanism.

Form as an alternative, stand also can have the support member that the block rubber that can move up and down is made, and are not only that the spring action of operating mechanism guarantees that cover plate returns and the seat returns so just.In addition, between stand and framework top side, can provide fixedly contact surface, with the motion that guarantees that cylinder has only limited, to guarantee the correct relative position between the tappet surface in tappet and the rotatable sleeve pipe.

For cover plate being remained on their open position, according to certain embodiments, this toilet seat is characterised in that, operating mechanism comprises another rotating sleeve pipe, its first end edge has the zigzag second tappet surface, the second end edge has the 3rd tappet surface, and described the 3rd tappet surface has dark, shallow slot alternately, second tappet engagement of these grooves and cylinder; The top side of the following and framework of stand keeps certain distance, make win tappet can only with situation that first tappet surface of first sleeve pipe contacts under carry out displacement.

When stand is in tip-up state and will be by user's manual activation the time, the downward press degree that this stand can may occur when interacting with stand further is pressed against on the framework.Thus, when first tappet contacted with zigzag second tappet surface, another sleeve pipe can rotate, and the described second tappet surface has the inclined-plane, can pass to second sleeve pipe with rotatablely moving.Simultaneously, by this continuous motion of cylinder, second tappet on the cylinder will shift out from the deep trouth of another rotatable sleeve pipe.

When another rotatable sleeve pipe rotates, second tappet and shallow slot alignment.Thereby make cylinder remain on its pressing position, simultaneously, the first rotatable sleeve pipe will remain on cover plate is forwarded on the position away from the ight soil opening.

Like this, when cover plate is in its retrieving position, just can be freely near the inside of ight soil chamber, so can maintain at described retrieving position upper cover plate, be that second tappet can remain on cylinder in the shallow slot on the 3rd tappet surface securely because under the effect of spring force.

When this latched position was released, the user only needed to apply once more directly downward pressure on cylinder.When this operation takes place, first tappet will be once more with another sleeve pipe on the zigzag second tappet surface engaged, making rotatablely moves takes place once more, thereby second tappet is alignd with the deep trouth on the 3rd tappet surface once more and can enter deep trouth.Therefore, first tappet passes through the first tappet groove to swivel motion, thereby cover plate is closed.

Owing under stand, have the confined space, so have following feature according to the described toilet seat of specific embodiment, promptly each in two cover plates all comprises a median plate part and an outer plate portion, and two control sticks are provided, each control stick all comprise two be used for above-mentioned two plate portions on the groove of pin engagement.

In addition, preferably make the mutual distant lateral edges of facing mutually of outer plate portion have crooked shape, this shape roughly corresponding to the circle of ight soil opening, just is used to cover opening on its closed position; Preferably make the lateral edges of outer plate portion have crooked shape, this shape roughly corresponding to the circle of ight soil opening, just is used to expose the ight soil opening on the position that valve is closed; Preferably make the lateral edges of outer plate portion have crooked shape, on the closed position, just be used to cover the opening that forms between the plate portion outside two.

By each cover plate being designed to two plate portions of its shape,, just can utilize the space of stand below well when the shape of outer plate portion during roughly corresponding to the stand width corresponding to the ight soil opening.

When plate portion outside these forwards its open position to, opposed facing lateral edges will be basically with the ight soil opening on fringe region overlapping, but withdrawal is slightly a bit polluted to avoid producing below stand.

If for attractive in appearance and adopted very narrow stand, can also further cut apart cover plate, make each cover plate all comprise three or more plate portion.Under the sort of situation, control stick will have the groove of the pin engagement on three or more and each plate portion.

The specific embodiment

In each different views of accompanying drawing, identical or corresponding element marks with identical numbering.Therefore in each independent view, all no longer provide special explanation.

In Fig. 1, can see the exploded view of each element that constitutes toilet seat parts of the present invention.Should illustrate that this figure does not illustrate cover plate and operating mechanism.

Toilet seat 1 comprises a cylindrical part 2, and this cylindrical part comprises and is positioned at the ight soil chamber 3 that is roughly cylindrical wall 4.Have a carriage 5 that supports foot pedal 6 on the cylindrical wall 4.

Cylindrical part 2 can be fixed on the rear wall and have a blast pipe 7, and described blast pipe 7 links to each other with extraneous air by the inside of hole 8 with cylindrical part 2.Also provide a pipe 9 in cylindrical part 2, this pipe 9 links to each other with mouthful 10 (see figure 10)s of urinating of urinal 11 bottoms.Urinal 11 has a upper opening 12.13 of openings belong to ight soil chamber 3.Well-bucket 14 shown in Figure 11 and 12 is made following size, that is, make it can pass opening 13.Well-bucket has one can be by around the outer rim 15 on the top edge zone 16 of the rear wall 17 that is arranged on urinal 11.Outer rim 15 is passed the groove 18 on the rear wall 17 of urinal.

Toilet seat 1 comprises a stand 19, and described stand 19 comprises the indenture 20 of the thigh location that is used to make the user.Stand 19 has the opening 21 that is roughly 8 fonts, and described opening 21 shows urine opening and ight soil opening 13.

Toilet seat comprises a framework 22, has ight soil opening 13 and urine opening 12 on the described framework 22, and in the illustrated embodiment, this framework 22 is made one with urinal 11.Stand 19 is suspended on the framework 22 rotationally by suitable assembly parts 23.

Stand 19 has a lid 24 that covers opening 21.Lid 24 can be made two parts that comprise child seat as illustrated, perhaps make a complete lid 24.Lid 24 is fastened on the stand 19 by rotatable suspender, and is fixed on the framework 22 by assembly parts 23.

In the illustrated embodiment, foot pedal 6 is positioned on the carriage 5.Carriage 5 can be provided with at various height, makes the position of foot pedal to regulate according to different users.Thus, just can allow the user mention pin and place the below of he self health, and make that to lay oneself open to almost be the position of squatting down, and this position is a desirable ergonomic position of loosening intestines.

Foot pedal can also allow children more easily use toilet seat.

Because what adopt is " two parts " structure with urinal 11 and ight soil well-bucket 14, this has just guaranteed the isolation of urine and ight soil.Therefore, urine can not polluted because of contacting with ight soil.

The framework 22 of looking from the below as can see from Figure 2, this framework 22 is in aggregates with urinal 11.Two cover plates 25 are provided here, and each cover plate all is made of an outer plate portion 26 and a median plate part 27.Each plate portion all is suspended on the pivot 28, and described pivot 28 is arranged on the rear portion of framework and is positioned at the both sides of the central plane that passes framework 22. Plate portion 26,27 will roughly rotate in the locational horizontal plane below being close to framework, because stand 19 abuts against the top of framework, rotates so plate portion 26,27 also is close to the below of stand 19.

This rotation realizes by operating mechanism 29.Operating mechanism 29 comprises a central cylindrical or cylindrical bar 30, and this cylindrical bar 30 is biased on Fig. 2 and the position shown in Figure 3 by the spring (not shown).Cylinder 30 comprises first tappet 31 and second tappet, 32, the first tappets 31 and surperficial 33 interactions of first tappet in the rotating sleeve pipe 34.Rotating sleeve pipe 34 is wrenched the face (not shown) by one and control stick 35 is rotationally connected, and described control stick 35 has a hole corresponding to the face of being wrenched in the cylinder.Therefore control stick 35 rotates with sleeve pipe 34.

Each control stick 35 all comprises first groove 36 and another groove 38, and first pin 37 on described first groove 36 and the outer plate portion 26 interacts, and the pin 39 on described another groove 38 and the median plate part 27 interacts.By revoling tube 34 and rotate control stick 35 thus, will make plate portion 26,27 turn to position shown in Figure 6 by position shown in Figure 4 from position shown in Figure 2.This rotation will be described hereinafter.On position shown in Figure 4, plate portion 26,27 turns to half-open position.Therefore, first tappet 31 will move a half-distance along the tappet surface 33 in the groove 40 of cylinder 34.Move by this, make cylinder 30 reduce (situation shown in Figure 5 of looking) from the below.By continuing to move to Fig. 6 and position shown in Figure 7, plate portion 26,27 turns to the position of opening fully, makes ight soil opening 13 expose fully.Cylinder 30 enters position shown in Figure 7 thus, and promptly first tappet 31 is positioned at the bottom on the maximum tappet surface 33 of sleeve pipe 34.

Normal state is when the user sits down, and the stand below is pressed to position shown in Figure 7 with cylinder 30.When the user when stand stands, spring force will drive cylinder 30 and turn back to position shown in Figure 3, thus, plate portion 26,27 will cover ight soil opening 15 once more.As Fig. 3,5,7 and 9 illustrated especially, operating mechanism 29 also comprised another rotating sleeve pipe 41, and second tappet 32 on it and the cylinder 30 interacts.

Another sleeve pipe 41 has the second tappet surface 42 at its first end edge, and this face is with sawtooth and inclined surface 43 engagements.This tappet surface can cooperate with first tappet 31, to drive 41 rotations of other sleeve pipe.By this rotation, the 3rd tappet surface 44 that is arranged on second terminal edge of sleeve pipe 41 also is rotated.Thus, the deep trouth 45 that second tappet will be located in when it normally uses shifts out, and moves to shallow slot shown in Figure 9 46.In this position, plate portion 26,27 will be locked in the position of opening.When need be, for example remove ight soil well-bucket 14 or in order to clean, above-mentioned state suits near the inside of toilet seat.Cylinder 30 can not can only activate by promoting stand by stand, and this feasible top stand that passes the cylinder of framework 22 needs manually to activate.

In the time will carrying out release, the user only needs to activate cylinder 13, after this, by with the second profile of tooth tappet surface 42 on inclined surface 43 engagement, first tappet 31 can make second sleeve pipe 41 rotate, thereby makes second tappet 32 align with one of deep trouth 45 once more.Thus, the normal operating condition shown in Fig. 2-7 occurs once more.

Figure 10 shows the user and should how to be sitting on the toilet seat and to make his thigh 47 place (see figure 1) on the indenture 20 of stand 19.Symbol shows respectively when woman 48 and man 49 are sitting on the toilet seat, and how urine discharges.Cross 50 has been indicated the position of defecation, and it roughly is positioned at the front portion of ight soil opening 13, makes the user behind defecation hand to be moved to the buttocks back and comes the wiping buttocks.

Illustrated toilet seat preferably has the length of 450-460mm from the front side of urine opening to the rear side of ight soil opening, and the width of two openings is roughly 205-215mm, and wherein the width of urine opening will be bigger than the width of ight soil opening.The external width of stand is preferably between 410mm and the 430mm.

Simultaneously, consider old man, stern disease patient and wheelchair user, the difference in height between plate 6 and the stand 19 is 460-490mm.Height between plate 6 and the stand 19 is about 200-300mm.These sizes provide best support to the user.

The maximum length of urinal and lateral dimension are preferably between 230mm and the 260mm.As Figure 10 illustrated especially, the rear portion of urine opening 12 roughly was the parabolic shape of continuous semicircle.The degree of depth of urinal 11 is preferably between 110mm and the 130mm.

As shown in figure 11, well-bucket 14 has a lid 51, and lid 51 has a handle 52.Lid 51 is preferably with the bayonet coupling device, and this device meshes with the corresponding intrument of well-bucket inside.Therefore the user can be moved down into lid on the well-bucket, rotates it, mentions well-bucket by the handle 52 of mentioning lid then.Ight soil well-bucket 14 can be removed at an easy rate thus and dirt is overflowed.

Toilet seat of the present invention is suitable for making by mold injection.But, also be fine with other method.Even preferably adopt plastics, also can adopt other materials to make the primary element of one or more formation toilet seat parts.If desired, can make stand 19 and lid 24 with timber.
